NEW YORK – The Defense Department's Joint POW/MIA Personnel Accounting Command said an exhaustive search by an expedition team of U.S. Coast Guard service members and North South Polar, Inc. Scientists and explorers has produced sufficient evidence that the crash site of a WWII Coast Guard Grumman Duck rescue aircraft missing for 70 years with three men aboard, beneath the ice near Koge Bay, Greenland, has been found, Coast Guard officials announced Monday.

By using historical information, ground penetrating radar, a magnetometer and metal detection equipment, the expedition team isolated the location where the aircrew crashed on Nov. 29, 1942. The team then melted five six-inch-wide holes deep into the ice and lowered a specially designed camera scope. At approximately 38 feet below the ice surface in the second hole, the team observed black cables consistent with wiring used in WWII-era J2F-4 amphibious Grumman aircraft.

Further analysis of video from the camera scope and photographs captured by a member of the expedition team revealed additional aircraft components similar to those found in the engine area of the J2F-4 Grumman Duck.

“Locating the J2F-4 Grumman Duck was a monumental success,” said Cmdr. Jim Blow, from the U.S. Coast Guard Office of Aviation Forces. “Collectively, the Coast Guard and NSP accomplished what the Coast Guard set out to achieve in 2008 when efforts began to locate the Duck.”

“The three men aboard this aircraft were heroes who made the ultimate sacrifice for their country,” Blow added. “The story of the Grumman Duck reflects the history and the mission of the Coast Guard, and by finding the aircraft we have begun to repay our country’s debt to them.”

Information was obtained, analyzed and cross-referenced to formulate the primary points of interest to search during the course of the Coast Guard-sponsored expedition.

It wasn’t until the end of the seven-day expedition that the team, utilizing the ground penetrating radar, swept an additional historical position and made the strongest radar contact. This ultimately led to the location of the Duck.

“It was an incredible experience to hear the team announce over the hand-held radio that they located aircraft components within the second bore-hole,” said Lou Sapienza, CEO of North South Polar, Inc. “We’ve spent nearly three years of research planning for this moment. There is nothing more meaningful than to have the family members of the lost aircrew know we’ve located the site of the Duck.”

The Duck’s last flight, with Pritchard at the controls and Bottoms serving as radioman, was an attempt to rescue seven members of a U.S. Army Air Force B-17 Air Transport Command crew that had crashed during a search mission on Nov. 9, 1942. On Nov. 28, 1942, Pritchard and Bottoms had successfully flown the Duck to rescue two members of the B-17 crew during an unprecedented landing on the Greenland Ice Cap. When the two Coast Guardsmen returned the following day, they picked up Howarth, the B-17’s radioman. They were attempting to reach the Coast Guard Cutter Northland when they encountered whiteout conditions and crashed. The wrecked Duck was first spotted a week later by a U.S. Army aircrew, which reported no signs of life. The remaining B-17 crewmen were sustained with air drops until they were rescued approximately six months later.

The Coast Guard is coordinating efforts with the Joint POW/MIA Personnel Accounting Command on future actions for this site.
